Natural-gas prices slip after U.S. supply data                                 (                                     NGX13                                 )                               

SAN FRANCISCO (MarketWatch) -- Natural-gas futures traded lower on Tuesday after the U.S. Energy Information Administration reported that supplies of natural gas rose 77 billion cubic feet for the week ended Oct. 11. Analysts surveyed by Platts were looking for a rise between 75 billion cubic feet and 79 billion cubic feet. The report had been delayed due to the 16-day government shutdown. Total stocks now stand at 3.654 trillion cubic feet, down 115 billion cubic feet from the year-ago level and 57 billion cubic feet above the five-year average, the government said. November natural gas     (ngx13)   was at $3.63 per million British thermal units, down 4 cents, or 1.2%. It was trading at $3.64 before the data.
